NAME

SYNOPSIS

INTERFACE LEVEL

Architecture independent level 1 (DDI/DKI).

PARAMETERS

mp

Pointer to the message whose blocks are to be concatenated.

len

Number of bytes to concatenate.

DESCRIPTION

msgpullup() concatenates and aligns the first len data bytes of the message pointed to by mp, copying the data into a new message.
Any remaining bytes in the remaining message blocks will be copied and linked onto the new message. The original message is unaltered. If len equals -1, all
data are concatenated. If len bytes of the same message type cannot be found, msgpullup() fails and returns NULL.
